Application filed August 10, 1915. Serial No. 44,807.

To all whom it may concern Be it known that we, EDWARD and JOHN E. JONES, citizens of the United States, residing at Scranton and Throop, respectively, in the county of Lackawanna and State of Pennsylvania, have invented certainnew and useful Improvements in Lubricators, of which the following is a specificatio v p This invention relatesto new andyuseful improvements in automatic lubricators, the object of theinvention being the provision of a lubricator for feeding graphite or any lubricants manufactured in solid form to the valves of steam engines, pistons of engines or any other moving parts for which such lubricant may be intended.

A further object of this invention is the construction of a lubricatorby means of which stick graphite may be exposed'to the action of a reciprocating cutter and the part of the graphite thus shaved off mixed with steam supplied to the lubricator and the mixed graphiteand steam fed from the.

lubricator to the parts being lubricated.

A still further object of theginvention is the provisionof a steam jetto the lubricator i "in such a manner that any steam pressure in the lubricator will not tend to hold the stick of. graphite out of engagement with the cutter mechanism.

In many instances, it is advisable to also supply a certain proportion of the oil to the graphite and steam and this invention'comprehends the provision of means by which an oil cup may be attached to the discharge portion of the lubricator in order that the oil may be mixed with the graphite and steam before it passesfrom thelubrioator.

Another object comprehended by this'invention is the provision of a novel form of cutting mechanism for shaving the graphite from the solid stick, together with means for suitably supporting the shaving mechanism for reciprocatory'movement, and means capable of attachment to a moving part of g the engine being lubricated.forreciprocating the cutting mechanism.

Other objects, such as the provision of means forholding the stick graphite in position to be engaged by the cutter and means for determining the quantity of graphite in the lubricator will appear andbe more fully A. Jones described in the specification and illustrated in the accompanying drawings which form,

together with the appended claims, a clear disclosure of the invention. I a

In the drawings: Figure 1 is a central vertical longitudinal sectional: view of the lubricator; Fig. 2 is a vertical sectional view fragmentary end elevation of the lubricator disclosing certain of the operating mechanism;-Fig. 4 is a transverse sectional view taken onthe line 44: of Fig. 2. Fig.5 is

a fragmentary vertical sectional view, showmg a. somewhat modified form of structure;

Fig. 6 IS a fragmentary elevational view,

showing a still further modified form of structure. p

Corresponding and like parts are referred to. in the following description and indiwise formed as a single piece and from any The arms,

suitable metal or other material. of this body portion are tubular in construction and the upper vertical arm 11 provides a chamber 12 adaptedto receive a stick of graphite or other lubricant, being of cross sectional shape and area to correspond to the cross sectional shape and area of the stick to be employed. This chamber is, however,

preferably somewhat greater in cross sectional area than the stick of lubricant and, at its lower end where it opens into the intermediate portion of the body is surrounded taken on the line 2'-2 of Fig. 1; Fig. 3 isa by an inwardly directed guide flange '13 which will snugly engage about the lower end of the stick of lubricant,.which stick is indicated by the numeral "14. The peripheral wall of the chamber 12 and alsovof the flange 13, is provided with a series of longitudinal leakage grooves or channels 15, best shown in Fig. 1, and the upper end of the arm 11 is reducedand externally thread- 7 ed to receive a. cap 16, a packing ring 17 being preferably interposed betweenthe "cap and arm to form a tightjon t. Thlscap 16 is formed centrally with, an opening and about this opening with an outwardly d1- .frate of feeding of the graphite, I provide rected threaded nipple 18. The stem 19 of a follower 20 extends through'the opening in the cap 16 and the follower, which engages against the upper end of the graphite stick 14, is provided with a depending perlpheral flange 21 surrounding such stick and guiding its upper end to keep the stick spaced from the wall of the chamber 2L2.

Any suitable packing 22 is interposed in the nipple 18 about the stem l9 and compressed by a threaded plug 23 which in turn isinclosed by, an outer cap 24. This outer cap stick l4 and .above the follow-er 2O inbrder that there will be .an equal pressure of steam against both ends of the graphite stick, wheigeby there fwill bc no tendency toward vmotion upon the part'of the stick, due -to unbalanced steainpressure. To control ,the

one or more weights 29 in the tormvof disks having radial slots toreceive the stem 19 and adapted, when applied. to the stem, to

seatv npon the fol-lower 20.

The lower rertical 'arm 30 is in diretaxial alinement with the arm 11,.is also tubular and is; externally threaded at its lower end for threaded engagement in the wall of a steam chest or similar structure to which "the ilubricator' is to be applied, a lock nuxt 31 being usually threaded upon the arm for clamp ng engagement against the wall of the steam chest. Intermediate its length,

,thearm 30 is provided with anioil receiving opening 32 surrounded ,by .a laterally ex 1 tending nipple 33 adapted ;.to be connected directly to an oil cup or a pipe-leading to ,a' suitable source oftoil supply.

a The horizontally disposed anms f85fof the body-#10 are also tubular and extend in axial alinement with each ;other,

each being externally threaded its free end to receive an inner cap 36 .tormed cen- "trally with an ppening 37 and in spaced relationabout this openlng with ianioutwardly directed externally threaded nipple 38 adapted toxreceive anouter cap 39 which forces a.clamping plug 40 into engagement wwith: packing 41, positioned in the V nipple 89' to ,formin effect a stuflingboxconstruc- ,tiOIL A shaft which, as -will be later explained, partially supports and forms an,

actuatingmeans for the cutting mechanism,

reciprocally mounted through the stuffling boxes thus provided, preferablyextend ing through both stufiing boxes, ,as shown, althoughcne end of the arm 3.4 may be closed and the "shaft shortened'to lie wholly within the lubricator at such end.

Secured to the shaft 42, by set screws 43 or other suitable means, are spaced "brackets 44 which are connected to and support a carriage formingplate 4.5,the edges ofwhich I project into oppositely formed guide grooves or channels 46 injthe walls ofthe arms 34: and 35! It will therefore be seen that these guide grooves prevent any turning move v ment of the plate 45 and that the brackets connectthis plate to the shaft 42 in such a manner that reciprocationof theshaft will cause reciprocation of the plate. The guide grooves 46 are so located and the brackets a4: so, proportioned that the plate is posi adjacent theclower face of the peripheral flange 13 -and, consequently, in such a position as to suppont the lower end of the graphite, stick l4. s The plate 45, intermetioned with its upper surface immediately c diate its length, .is provided with a pair of transversely extending spaced slots 46 andthe portion ofthe plate defined between these slots has its edges .upbent to ,form cutting edges t7 extending transversely of the plate and throughoutthe length of the opening between the wallsof the flange 13. It will 7 of course be understood that, if desired, the

plate 425 maybe -merely foamed avith slots or perforations and a' separate cutting blade,

of any suitable type, may be secured to the upper. face of the. plate. The :stnucture shownis, however, much simpler and more j economical.

{As acgmeans for reciprocating theshaft, 4:2, thearmi35 oft he body-is provided'with a downw r y lp 'si c na ar n a 1111k 49 is pivotally connected at one end to the ear atits opposite end to the intermed ate portion-eta l-everQ, the vlever 50loe1ng of connection between the link and lever smav be variedhe adjacent end of the shaft 421s reduced and screw threaded, as

.fiirn ed with a plurality of spaced pivot receiving openings 51 In order that the point shown at .52, to receive a clamping nut 53 secured in place by alset screwv 51- Located between this nut 53 and theshoulder formed byreducing-theshaatt i2, is a sleeye5v5 having trunnions 256 which engage in bearings I formed in the arms of fth e ifqrked terminal 57 of the lever 50.. Washers .58 are preien v ably interposed between the ends of the sleeve 55 and the shoulderofthe s'haftand nuti53 to take up for wean .A link .59 is connected to the free end of the lever 50 and is adapted to be connected in any suite an manner toa moving part of ail-machine or other 'rnechanlsm to be lubricated.

In describing the operation .of the lubrileator, it will be assumed, t the 'sakelof amass hat it e o empl yed in 111 bricat ng the sl de valveoi a steamengine, although of course it may be employed for otherpurposes with equal 'eliiciency. When so employed, its arm 30 will be threaded into a tappedbore formed in the cap plate of the steam chest of the engine and the nut 31 turned home to tightly secure the lubricator in place. The link 59 will be connected to some suitable part of the engine, such as the valve stem and. a pipe 50 will be led from any suitable source of steam supply and will terminate in branches 61 and 62 communicating with the passages 27 and 28. Preferably, the pipe 60 will lead from the dry pipe between the throttle valve and engine cylinders so that when the engine is running idly, there will be no steam admitted to the lubricator as there is, at that time, no occasion for utilizing a steam feed of the lubricant as the partial vacuum created by the cylinders will take care of the feed of lubricant.

It will of course be clear that with the equalizing or leakage grooves 15, it is not absolutely essential that steam be supplied above the follower 29 through the branch62 of the pipe 60 as steam may pass through these grooves into the space above the follower. On the other hand, it will be clear that if steam is supplied both above and below the graphite stick, the grooves are not absolutely essential. However, it is better to provide both means for holding the graphite stick in place so that in case of failure of either one to operate properly, the other one may still prevent failure of the device.

It will be clear that reciprocation of the valve stem will act through the link 59 and lever 50, the latter employing the link 49 as a fulcrum, to reciprocate the shaft 42 and, consequently, cause the cutter blades 47 to pass back and forth across the lower face of the graphite stick and shave graphite therefrom. The steam entering through the pipe 60 will take up the graphite shavings thus formed and drive them through the slot 4L6 and into the arm 30 of the lubricator and so to the part being lubricated. Oil may, of course, be supplied through the passage 32 to the mixed steam andv graphite on its way from the lubricator.

Although we have illustrated and described our invention in all its details, it will of course be understood that we do not wish to be limited to such details, as various minor changes, within the scope of the appended claims, may be made, at any time, without in the slightest degree departing from the spirit of our invention. For instance, in place of using the weight 29 shown in Fig. 1 of the drawings, the outer end of the stem 19 of the follower 20 may seat in a socket or bore formed in a weight 65 which is secured to the stem by a set bolt 66, this form of construction being illustrated in Fig. 5 of the drawings.

In Fig. 6 of the drawings we have illust'rated a construction by means of which the amount of graphite remaining in the lubricator may be read at a distance. This includes suitable scale 67 located at any desired point and cooperating Withthe scale is an indicating needle 68 carried by oneend of a cord 69 which is trained about suitable pulleys or rollers 70 and at its free end attached to a ring 71 carried by the upper end of the stem 19.
